In said former application I have A the main levers, B the extension-levers, O referred to the fact that the main levers shown the even levers, and D the fifth lever, through therein instead of being suspended from which connection is made with the beam in stands on the bench-walls are suspended from the usual way.

As shown in Fig. 1 subject-matter of the present invention. In and also in Fig. 5, pocket portions or recesses a scale of that character on account of the are provided, and one side of the channel-irons 0 close relation which exists between the rail on the longitudinal walls rests through their 45 and the sliding horizontal plate which rests length upon the coping, which is formed to on the platform I-beams it is necessary that receive them, the ends being supported upon some provision be made to preserve this rethe coping, but the point of support of the main levers being within the recesses or pockets X. Bolted to the under side of these channel-irons are yokes or brackets H, constructed, preferably, as shown in Fig. 3, with inturned flange a, to be bolted or riveted to said channel-irons, and through the central part of said yoke, which is made very strong, is passed an eyebolt I, secured to said yoke. To the eye of this bolt is secured the loop K, from which is hung one end of the main levers A. In the usual manner the platform P is supported by I-beams L, which have V-bearings fitting the knife-edges b on the mainlevers. The opposite ends of the main levers A are hung from the extension-levers B, connected to the even levers O in the usual way, and from these a fifth lever D leads to the beam through the usual connections. M represents the flat bars of iron sliding horizontally upon the top of the platform, Which are manipulated out and in, as described in the aforesaid application, to receive the flanges of the wheels of the cars and transfer the weight thereof to the platform.

In Fig. A is shown a modification of the manner of hanging the main levers to the coping, in which a cast-steel bar N is secured between two layers of masonry of the coping, extending longitudinally beyond the adjacent vertical Wall of the coping, and the eyebolt supporting the loop, which supports one end of the main levers, is secured to said flat bar.

It will be understood that so far as the construction of the supporting means is concerned, although it is of importance and is herein claimed specifically, it may be varied, the broad idea of the invention residing in the hanging of the main levers from the coping which supports the rails or from the channel-irons upon which the rails are placed, the platform being supported on the main levers, whereby no matter what reasonable displacement of the coping may take place the relative relation of the platform to the track and therefore the relieving mechanism on the platform will all remain the same.

1. A weighing-scale having longitudinal walls, with recesses intermediate their ends, yokes or brackets supported by the walls and arranged within the recesses, transverse levers pivotally hung from said yokes or brackets, said pivotal connections being within the recesses of the walls, longitudinal levers connected with the transverse levers, a beam-lever connected with the longitudinal levers, and a platform mounted on the transverse levers; substantially as described.

7. In a weighing-scale having a suitable wall with reduced portions forming pockets, suitable channel-irons secured to the wall and overhanging the same, yokes secured to the channel-irons and hanging directly beneath the same within the pockets, main levers suspended at one end from the yokes, means for supporting the opposite ends of said levers, and a platform supported on the main levers; substantially as described.

8. In a weighing-scale havinga longitudinal wall with reduced or cut-out portions forming pockets, supports resting on the said wall, brackets hung from said supports within the pockets, levers hung at one end from said brackets, means for supporting the opposite ends of said levers, and a platform supported on the levers; substantially as described.

9. In a weighing-scale, having a suitable wall, channel-irons whose outer edges are secured thereto and overhang the same, yokes secured to said channel-irons, eyebolts secured to said yokes, main levers hung from said eyebolts, and a platform resting upon the main levers; substantially as described.
